DTC 1-3

DTC 1-1: Front Vertical Acceleration Sensor Circuit High Voltage

DTC 1-2: Right-rear Vertical Acceleration Sensor Circuit High Voltage

DTC 1-3: Left-rear Vertical Acceleration Sensor Circuit High Voltage

1. Turn the ignition switch ON (II).
2. Clear the DTC with the HDS.
3. Turn the ignition switch OFF.
4. Start the engine, and wait 5 seconds.
5. Check for DTCs with the HDS.

Is DTC 1-1, 1-2, or 1-3 indicated?

YES - Go to step 6.

NO - Intermittent failure at this time. Check for poor or loose connections between the vertical acceleration sensor and the active damper control unit.

6. Turn the ignition switch OFF.
7. Disconnect active damper control unit connector B (14P).
8. Turn the ignition switch ON (II).
9. Measure voltage between body ground and the appropriate active damper control unit connector B (14P) terminal (see table).





Is there more than 0.5 V?

YES - Repair short to power in the wire between the appropriate vertical acceleration sensor and the active damper control unit.

NO - Go to step 10.

10. Turn the ignition switch OFF.
11. Reconnect active damper control unit connector B (14P).
12. Do the appropriate vertical acceleration sensor inspection.





Is the vertical acceleration sensor indicate OK?

YES - Replace the active damper control unit.

NO - Go to step 13.

13. Turn the ignition switch OFF.
14. Disconnect the appropriate vertical acceleration sensor 3P connector.





15. Disconnect active damper control unit connector B (14P).
16. Check for continuity between the appropriate vertical acceleration sensor terminals No. 1 and No. 3.





Is there continuity?

YES - Repair short in the wires between the appropriate vertical acceleration sensor and the active damper control unit.

NO - Go to step 17.

17. Check for continuity between active damper control unit connector B (14P) terminal No. 11 and appropriate vertical acceleration sensor 3P connector terminal No.2 (see table).





Is there continuity?

YES - Replace the appropriate vertical acceleration sensor.

NO - Repair open in the wire between the appropriate vertical acceleration sensor and the active damper control unit.
